Title: Improvements in or relating to fire extinguishers and fire alarms
IPC: A62C8/00
Filed: 1933-03-10
Abstract: 416,085. Fire extinguishers and alarms. JONES, F. HAYES-, and DURSTON, G. H., 150, Southampton Row, London. March 10, 1933, Nos. 7291 and 30127. [Classes 47 (i) and 47 (ii).] A grenade is fitted with a metal cap provided with radially-projecting pins, similar to or identical with those provided on the caps of electric lamps, for co-operation with a fixed socket provided with bayonet slots, either the cap or the socket embodying a fusible joint. Thus, the grenade is readily removable for hand use, and is automatically released in case of fire. As shown, Fig. 2, the grenade 12, filled with carbon tetrachloride, is fitted with a metal cap 16 approximating in dimensions to the caps of ordinary electric lamps, the pins 18, however, being of fusible metal. Such a grenade can be inserted in any ordinary electric lamp socket, and will fall when the pins fuse. The top of the cap is covered with insulating material. Grenades of large capacity are reinforced by a wire net 20 secured to the cap 16. Alternatively, the cap may be made in two parts united by fusible solder, the upper part carrying non-fusible pins. In modifications, the fuse is incorporated in a two-part socket which is generally similar to an ordinary electric light socket. In Fig. 3, the part 22 of the socket formed with the bayonet slots 24 is soldered at two or more points 38 to the flange 32 of a sleeve 26, which is secured by a ring 28 to an adapter 56 screwed on to any standard fitting 58. The usual spring pins 40 of such a socket are modified in that one carries a distance piece 48 and a metal washer 50 adapted to make contact with a metal extension 52 from the other pin. When a grenade is inserted in the socket, the pins are raised, breaking the contact 50, 52. In case of fire, the part 22 falls off with the grenade, and contact is made at 50, 52, closing an alarm circuit. In a modification, the parts 22, 26 of the socket are soldered at one side only, having a hook and slot connection at the other side. - In other modifications, the part 22 is housed within the part 26, the latter being shrouded by an insulating skirt. In other modifications, the part 22 is formed with holes or open slots which fit over pegs projecting from the part 26, the parts then being held together by fusible dowels passing through the pegs. In another modification, Fig. 12, the part 26 carries headed fusible pins 82 which co-operate with arcuate keyhole slots 80 in the part 22. Rotation of the part 22, as by a cable 86 and remote control, thus provides a manual release for the grenade. According to the first Provisional Specification, the socket may be mounted at its upper end upon a pin which can be withdrawn by means of a remote control. According to the Second Provisional Specification, the pins may be on the socket and the bayonet slots on the cap of the grenade.

Patent GB-1347945-A (GB)
Title: Telecommunications exchange systems
IPC: H04M15/04
Filed: 1972-02-17
Abstract: 1347945 Automatic exchange systems SIEMENS AG 17 Feb 1972 [25 Feb 1971] 7496/72 Heading H4K In an exchange through which local or trunk calls can be set-up, the latter calls each utilize an additional relay set located in the group selector so that the extra components required for multimetering need not be provided in all the exchange relay sets. The setting of the metering components is effected from a central control via a path which includes the normal (local) relay set and a part of the path through the group selector which will subsequently be used for speech. The switching network utilizes relay crosspoints. A calling subscriber Tn is initially connected via a line link frame T and a local relay set A to one of a plurality of free registers R so that dialled digits can be stored preparatory to processing by a central control Z. In the event of a local call (and indeed in the event of an incoming call or a tandem call involving relay sets C1, C2) the central control sets the first group selector RZ via marker MZ and then (for the first two types of call) the line link frame T via marker MT. Thereafter, when the called party replies, metering is effected with the aid of timed pulses supplied from a not shown source through the relay set A to the caller's meter. Alternatively metering is effected by a single pulse supplied from the register via wire w, or by a single pulse also supplied via wire w but intermediately stored in the relay set pending the called party's response whereby the register may be released for use on another call. If the call is to another exchange however, the central control seizes an appropriate outgoing trunk D and sets up a path thereto via the two wire first group selector RZ, a 2/4 wire converter G in a multimetering relay set E, and a four wire second group selector RV. The metering tariff determined by central control is intermediately stored in the register and then supplied as a pulse sequence via wire v and first group selector RZ to a pulse counting relay K in the metering relay set. (The tariff may be transmitted in a multipotential/current code or in a parallel code using both speech wires.) Consequently relay contact k is stepped to that lead P which supplies metering pulses at the rate appropriate to the call. The speech path is cut-through at e and the metering path, which may include either the speech wires or a special wire switched through therewith, is completed by the closure of contact h upon the reply of the called party.
Patent GB-447792-A (GB)
Title: Method for the production of substituted benzyl carbinamines and product thereof
Filed: 1935-03-11
Abstract: Substituted benzyl carbinamines having the formula C6H5.CH2.CHX.NH2 where X is an alkyl or alphyl group are prepared by electrolytic reduction of a benzyl ketone oxime.  Benzyl methyl ketone may be prepared by heating the calcium salts of phenylacetic acid and acetic acid; the ketone after separation is converted into its oxime by treatment with hydroxylamine in alkaline solution.  This is reduced electrolytically in the presence of sulphuric acid for production of the corresponding amine sulphate, which is then treated with alkali to free the amine which separates as an oily layer which may be decanted off.  This is dissolved in hydrochloric acid and oily impurities removed for example by means of isopropyl ether. The hydrochloride solution is treated with alkali to separate the amine which is then distilled.

Abstract: 1473041 Optical bar code reader MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 25 Feb 1975 [26 Feb 1974(2) 4 March 1974(3)] 7801/75 Heading G4M An optical bar code reader produces a plurality of scans crossing at a common point using a rotating mirror and a plurality of fixed mirrors. Light from a source 11, passing through apertured disc 36, is focussed at 15 and reflected by mirrors 16, 17 to pass through a hollow and rotating tube 18 carrying a mirror 19. Arranged on an imaginary circle around the tube 18 are mirrors 24-30 arranged to reflect the rotating beam to produce a respective one of scans 34 at a support 43 across which label-carrying articles, e.g. at a supermarket, pass. Light from the label is diffusely reflected and sensed by sensor 47, 48 which feeds a signal via 44 to processing circuit 45. Circuit 45 amplifies and shapes the signal to feed a pulse generator 63, a clock pulse generator 68 and a preset signal generator 69. Pulse generator 63 provides a plurality of pulses during each bar or space so that width of the bar or space can be determined. The clock pulse generator produces an output after each character of seven bits is read. The count indicating the width of each bit is stored in respective preset counters 65. At the end of each character, signals C3 are supplied to the counters so that the counters containing the larger initial values overflow and feed decoder 66. This converts the overflow signals and the zeros received into a 1 out of 10 and a parity bit signal which decoder 67 converts to a b.c.d. signal.

Title: Improvements in and relating to method and apparatus for generating and discharging foam
IPC: A62C5/00
Filed: 1958-03-12
Abstract: 871,966. Making foam. UNION CARBIDE CORPORATION. March 12, 1958 [March 14, 1957], No. 7900/58. Class 14 (1). [Also in Groups XVIII, XXI and XXVIII] In a process of or an apparatus for producing foam, a foam generating solution is in intimate contact with a propellant which is present in both liquid and gaseous phases, the propellant liquid phase being immiscible with and of greater density than the foam generating solution, and the foam generating solution and propellant, under the pressure of the gas phase propellant, are passed through separate orifices into a foam generating chamber where they become turbulently mixed to generate foam which is discharged from such chamber by the propellant. The propellant may be a halogencontaining hydrocarbon, e.g. dichlorodifluoromethane, bromotrifluoromethane or chlorotrifluoromethane, and the foam generating solution may comprise water and foaming agent, e.g. a 1% to 5% by weight solution of sodium alkyl sulphate. The apparatus described comprises a container 12 having a dip tube 24 communicating with an outlet hose 46 through a spring-closed trigger-operated valve 26. A tubular foam generator 51 slidable over the lower end of the dip tube 24 has a wide baffle 52 and is of a density such that it floats with the baffle 52 at the interface between the liquid propellant and foam generating solution whereby the baffle 52 separates the two liquids. The foam generator 51 is attached to a rod 35 within the dip tube 24, the upper part of the rod 35 passing through a hollow stem 25 of the valve 26 which is surmounted by a glass cap 31 within which the upper tip 44 of the rod 35 is visible when the correct amount of propellant liquid is present. When the valve 26 is opened to operate the extinguisher the foam generator 51 is forced upwardly into sealed relationship with the bottom of the tube 24 and foam generating solution passes into the foam generator 51 through pairs of diametrically opposed circumferentially spaced holes 54, Fig. 3, whilst propellant liquid passes upwardly through a passageway 58 and orifice 57 for turbulent mixing with the foam solution to form a foam which passes up the tube 24 to the outlet hose and nozzle 46, 48. A flow-restricting orifice 69 in the tube 24 may be provided to enable a shorter hose 46 to be used. In another embodiment, Fig. 5 (not shown), means for determining the level of the liquid propellant comprises a ball float gauge provided in the wall of the container in the region of the propellant liquid/foam solution interface. In a further embodiment the foam solution enters through orifices 154, Fig. 6, in the tube 24 and rises to a foam generating section 155 of the tube where it turbulently mixes with propellant gas entering an orifice 157 from the gas space above the foam solution.

Title: Improvements relating to polyphase alternating current motors
IPC: H02P1/26
Filed: 1933-03-17
Abstract: 403,546. Alternating-current induction motors. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and BALL, R. D., Phoenix Works, Bradford, Yorkshire. March 17, 1933, No. 8127. [Class 35.] In a polyphase alternating-current motor of the type having a phase of its primary winding adapted to act as an autotransformer for stepping up or stepping down the phase voltage for application to a condenser, an auxiliary winding is connected to the main phase winding and displaced in phase relatively thereto. In Fig. 2 (Prov.) each main phase M1-M3 is associated with an auxiliary phase A1-A3 displaced 90‹ therefrom. With the switch S in the starting position the ends Q1-Q3 of the auxiliary phases are connected together so that the main and auxiliary windings are in series in a star connection and the phase voltage is applied to each of the condensers C1-C3. For normal running, the ends P1-P3 of the main phases are connected to the star point. The numbers of turns and the phase angles of the auxiliary windings are preferably such that the voltage impressed on a condenser lies between the phase voltage and the line voltage. To avoid opening the motor circuit during the transition from starting to running, the switch S may connect all six points P1-Q3 momentarily. By employing the circuit shown in Fig. 1 (Comp.) the motor windings may be delta connected for running and two condensers C1 &c. in series may be associated with each phase. Fig. 3 (Prov.) shows a further star-delta arrangement in which the auxiliary windings A1-A3 have a phase displacement of approximately 60‹. The condensers are connected across the main windings as shown or across the auxiliary windings. In a modification of this arrangement, the line terminals T1-T3 are connected to the junctions of the main and auxiliary windings and the condensers are connected across both windings. During normal running, the circuit is substantially the same as that shown in Fig. 1 (Comp.).
